THRASHING-MACHINE CONSTRUCTION.

Application filed March 19, 1927.

This invention relates to a rain thrasher, and has forits primary object the provision of operat' ig mechanism supported. in a novel manner by a specially designed frame the latter not only supporting the mechanism but etior ivcly embr: chip and resisting all the usual strains to which a L rain thrasher is subject in the use thereof.

An, object of the invention is to so design the mperating mechanism that the same peri'ornis th 1 dual function of eliiciently operatthe various parts and :nibstantially holding the various parts associated and in proper alignment.

An object of the invention is the construction oi? novel.operating mechanism in. which the various parts are so designed. and connected that all hearings are exteriorly arranged to be readily accessible.

Another obj ect of the inven .ion is the provision of novel supporting and actuating mechanism whereby the parts actuated and associated. therewith may have a more compact arrangement to lower the center ol gravity of the machine as a whole.

Besides the above, my invention is distinguished in the substantial manner in which each part is designed. and coacts with its associate parts so as to perform its own operation very etliciently and further coarts to materially reinforce the thrasher throughout, thereby greatly prolonging the life of the thrasher.

A feature of my invention is the novel man nor of arranging and connecting the various rods so as to assure the proper alignment and correlation of the parts and actuating the same by suitable mechanism exteriorly a: anged for inspection at all times.

Another lcature of my invention is the novel design and association of the component parts that not only assures ofiicient operation but reduces friction to a. minimum.

"il'ith these and other objects in view my invention will be better understood from a description of the same when taken in connection with the accompanying drawings, wherein Figure 1 .is a sideelevation of a grain thrasher constructed in accordance with my invention Figure 2 is a sectional iew;

ing A con'ipletely embraced and reinforcecl in all directions by soecially designed trame l1 which in turn exteriorly supports the movable parts and bearings ot the novel construction of operati gr n'iecl anism (l, the component parts of which are so eonipac associated that the stra y racl; l) and gr. pan E have a very compact arrangement so as to ti'lnction with the other parts oi e thrashing machine in a manner to materially lower the center at gravity of the thraaher.

Referring to the drawi (5 more in detail, it will he noted that the housing is e? suhstantially rectangular :onlieuratimi to Vide the top 1 and aides 2 preteralily 'i' or from sheet metal so as to not only pro :1 more substantial eousti-ne ii'ni hut in i the same fireproof. It wil lei-ring to Figures F and (3 that the lioueiini'j is open at the bottmn as indit The il rame l is construe l i to c'tl'ettiyely embrace and he red to the sides and top of the housingand to extend a predeternlined tilHl'llllt below the housing to Slll lpfil'ii various operating etrueturee ol' the thraslnuf. This traine ll, as illustrated.

consists of a iair o't u )ner channel bars I 1 i eke I 2 he noteu hy reone or each side ol the tlu'eaiher ane. a pair of lower channel bars 5.. one on eaeh sale at the thrauher. 'lhesc bars are ellectivel s parallel and are secured to the top ot housing. As the various bars are riveted the housing. it will. be appreciated that the i and side walls are iyely' held against displacement and cap: hle (it fully withstanrling the usual strains to which a structure ot this character is subject in the use of the thrasher and turther to substai tially resist any tendency of the movable parts to move out ot their proper position.

I wish to call particular attention to th nm-el manner of forming the joints between theeroas liars and the Yertical bars which consists in overlapping portions ot the vertical barsand cross bars to he bolted together, as indicated at 8 and utilizing a clip 9 tor increasing the 'tl'-ecive engage-- ment hetween the bars. To con'iplele the lran'ie, I arrange properly placed braces to materially reinforce the frame.

"The operating: mechanism one of the f. -1 e t n 1m most important (a airs o. i.e machine eoi'istruction new under thiilfstltl'zwtion, is so deaigned and supported by the frame that all bearings and the oil cups thcre't'or are exteriorily arranged so as to be readily accessible and to enable the operator to readily View the :ction ol the movable parts.

I will first describe the hanger constructions for properly supportin the straw :LClC and grain pan tor oscillatory movements and then describe the actuating necha-iism for giving such oscillatory movemen s thereto. The grain pan hanger ll. is rl' i'tly dillerent in construction from the straw rael: hanger 12. 'l here'torefihe tw structures will he des-arribed separately. Th hanger structure ll comprises a lararing p 13 bolted to one of the vertical bars and their pro" videsl with a l'hmgre l'ltor enilu' Jug: a. r of the vertic: l b. r, and thus this plate is efteetively held against dislocation and capable of substantially withstamling all *ains to which the same tore, are providml with oil duets l8 Vertieahy of posed and readily accessible due to their location. The pin 1? lat rigidly secured thereto one end or a. link 9 the t as e'i'iu at which loosely receives the prot-ri ngr end of a har 20, and as the end is i uio-untwl on the har the same is yn'ovided with a Verti- (wally arranged oil duct 21 in an aceejsilale posit ion.

At this point I wish to call attention to th tact tha t although aiu describing the :a porting; cola-traction tor one end oi" the hammer, ll 0 construction on the other side at the thrasher is idenlieal. .eu ed to the L lie-ts one on each Side oi the 'e rain pan and provided with sockets 23 receiving: the bar 2i) and encore-ii thereto by the set screws 2 1; and thus it will appreciated that the plate and rod are lly connected together and as the plates arr rigidly connected to the grain pan by the root it will i that he apprewatta these parts must iliunetion yn'operiy as t are rigidly emineeted in their proper as; ciated positions. it will also he appreeialed that the emistruetiou is such that the grain pan is mate 'ially reiutorecd in a hsyerse direction and the same in rigi-zlly ipporled 'l'roni the frame and thus strains in any direction are properly taken care of.

As will he noted in Figure 2, the straw rack is arranged directly above and in parallel relation with the grain pan and the respective operations of the straw rack and grain pan are such that they may operate in a inanner to allow the straw rack and ain pan to be compactly arranged to minimize space or the purpose heretofore set forth.

Referring more particularly to'Figure 7,

will he subject when in 27, 28, 29 and 30, it will be noted that I provide a second rod 26 for the straw rack hanger which extends in imrallelism with red and is connected to the straw rack and associated parts in a way to substantially reinforce the straw rack in a transverse direction and to transfer the strains of operations of the straw rack to the substantially constructed frame. To accomplish this desired result, a pair of socket members 27 are secured upon opposite sides of the straw rack with their sockets 2S rigidly secured to the rod 26 by the set screws 29. The protruding ends 30 of the rod are rigidly mounted in the socket 31 by the hind ing action of the set screw 40.

.lilach arm of a special construction to function with a clip 33 in a manner to reduce friction and wear to'a minimum. To accomplish this desired result, the arm is provided with .a cup-shaped hub 34 embracing and onclosing for the proper frictional contac a bearing35projectingfromthe clip 33. Abolt 36 effectively secures the hub to the hearing I and is adjustable for compensating for wear.

The oilcup 37 is so disposed as to be readily accessible and feeds the oil properly to the contacting surfaces between the bearing 35 and hub 34. The clip 33, which may boa casting, is effectively secured to the upper suppi'irting bar 4- by the b s 38 and this clip is further provided with a flange 39 engaging the under surface of the bar 4, with the result that the clip is effectively held against displacement and is capable of rigidly resisting the usual strains to which a device of this character is subject.

The actuating or operating mechanism for the straw rack and grain pan as its component parts designed to extend entirely across the straw rack and grain pan and rigidly secured to the upper supporting bars 4, with. the result that the forward portions of the straw rack and grain pan are substantially reinforced in a transverse direction and the bars 4 are effectively secured together in a transverse direction at an intermediate point for substantially resisting the usual strains. The mechanism is also designed to have all bearings exteriorly arranged and con nected in a novel manner to the power device of the tractor to have all parts readily accessible and visible at all times.

This operating mechanism comprises a support rod 41 extending clear accross the thrasher to be rigidly secured on the brackets 42 secured to the bars 4 in a manner to have the protruding ends 43 positioned exteriorly are so disposed as-to be operatively associated with other parts of the mechanism, and to accom plish this desired result the arm 417'is provided with a socket 49 provided with a vertically disposed oil cup 50 and loosely re- 70 ceiving the protruding end 51. of a transversely extending straw ra :k rod 52. This rod 52 is rigidly mounted in, the sockets formed on :3 plates 54 arranged at opposite sides of the straw rack. The plate 54 is of a novel de- 7 sign, as shown in Figure 19, and provided with a Vertical flange 55 bolted to the side bar of the straw rack and a horizontal flange 56 secured to the under surface of the side bar.

I wish to call particular attention to the fact that the forward end of the side bar of the straw rack is cut away to snugly receive theflange of the plate 54 and to provide a shoulder 57 abutting theend of the side bar, and thus the plate is very effectively and sub- 85 stantially secured to the side bar so that strains from any direction may be effectively taken care of. The arm 48 of each bell crank is provided with a socket 58 rigidly secured by means of a set screw 59 to the protruding end 60 of the power rod 61. This power rod also extends transversely of the thrasher to position its ends 60 exteriorly of the frame, and as the rod is effectively secured to the bell cranks on opposite sides of the thrasher, it will be understood that this rod 61 performs the dual function of tying the various parts eifectively together and to provide power for operating the bell cranks through its connection with the prime mover.

it will also be noted that the rod (Si is posh tioned below the bottom of two in number, and effectively secured to cranks 63 of the crank shaft that carries ms the usual pulley 65 for furnisliii to the mechani is provided with an oil cup ()6 so d to be readily accessible. It will. also he noted that the crank shaft (34 is mounted in hearing elements (37 also COBDOCtCi'l to certain of the vertical bars, and thus the prime mover is also supporteiil from the ir ing elements exteriorly arranged accessible to receive oil in the vertically posed oil ducts therein. v

The grain pan actuating iii-eel lnisni ali-o consists of a rodGS of a length to extend cl across the grain pan and frame to ha re p. otruding ends 61) exteriorly arranged. This rod (38 rigidly scciu'cd to the hubs @"0 of brackets 71 by the set screws 72?. lniacket is provided with horizont tical flanges 73 that eifectivel i eare secured to the bottom and le bars of 5 grain pan. Thus it will he appn 'ited that a rigid connection is established br ween the two side bars of the grain pan thro: h the medium of the brackets and their ri nection with the rod (38, thereby materially reinforcing the grain pan in a transverse di rection and assuring}; the proper functioning thereot due to its pro cr Jaigement in place all times Clips 'i-l; arerigidly scoured to the bars 1; and each is p rovidcd with flanges 75 engaging under the bars l to cooperate with the rivets or bolts to reinforce the clip against displacement and to withstand the usual strains to \a'hich. a device of this character is subject. This clip 'iis also provided with a hearing "it; loosely receiving the hub 77 on the arm, To that is held in place by the bolt 7, that not only holds the hub properly .'a place but is capable of compem l provided w it.

satingr for wear, 'llhe hub it with oil cups 80 so disposed as e readily ll. "31). H 'j aiHfli wmgi accessi e. a u a1 n! to is use 1 cu. en 1 end 69 creto by t 1c rain pan,

a soclrdl fill receiving; the prot" the setscrew 82, and thus b aclict 'l'l rod (ill, and arm s icured together as a unit and in their properly related positions.

For the purpose ot transmitting motion from the hell cranks, provide the connecting tie rods Eli-l ha /in Bearing and 2-35 at th air ends provided with verii {any disposed oil ducts 8i; readily tl(.7(3L-Hi-llill0. One hearing; til; is mounted upon the protruding end. (ii) of the rod 8 and the other l i115; engages a pin 87 rigidly carried by lies associatedhell crank lever.

With the lllCtfllfil'llSlll i 'tdcs'azril ied, motion is t 'ausmitted in a substantially areuate mannor both to the grain pan and straw racl; il'rom a single power rod, which in turn is cl? il'ectively and substantially operated by pilniou receiving power trom the usual crank shalt.

To complete the invei'ition, l arr: nge the usual blower lltl, shatter Si and conveyor 90 on the lower supporting bar I which in turn is supported on the rear wheel structure 91, and thus it will he :urpreciatcd that all movable parts and inechanisn'is are mounted on two sets ol superimposed supporting bars, which in turn tffil'ljfiilltly 2 re supported upon the rear wheel. structure 91., with. the upper set ol suipportingg bars turther sur ported by the trout whee strurtureffiil. it will be noted that this trout wheel constriuaiion 92 includes rcarwardly inclined struts 5) connected by clips 9% to an intermediate inn-lion ot ,he upper set oi support bars.

Having: clearly illustrated described my invcntii'm, it will be tliully zppreciated that I provide a cmiatructiian that is rigid tlufmurhout and ot a design that tie various parts are more com 'iactly arr-an; to materially reduce the center at grainy oi the thrashe' as whole. l1 will. also h, apple ciated tha, all l)('32ll'lll and oil ducts are exteriorly ar 'anged in positions to be readily accessible and movable parts are visible at all times so as to readily convey to the operator the relative action of the parts. This is of material advantage in this particular art, as it informs the operator as-to the etficient operation of the various parts so when occasion arises minor adjustments may be made readily to assure the operation oi the machine at all times with full etlicienc Upon driving of the pulley by any construction of prime mover, such as aFordson tractor, the cranl: shaft G l; will be rotated for reciprocating the pitinen 62., which in turn oscillate the povvr or support rod (31. As this red (ii is connected to the lower arms of the he l 0 "am; levers on opposite sides of the tl rasher, the bell crank lovers will he oscillated about thi protruding mds of the sta- .s i ish to call mrticuhu' attimtion to the \1 lac that all oil cups or oil ducts are arranged H1 their most advantageiius position totake adva itage oi gravitational action and to al- 1 \1 V sow ready accmiiuhility thereto, and as the 'arious parisare oi" a rigid construction assembled together in a ri -id manner, it will he understood that the li c of the various parts is materially increased, but should occasion arise to renew part this can be very readily taken care ot due to the exterio arrangen'ient oi the parts and their mode ol connection to associated parts. I wish to further call attenth n to the rigid manner in which the grain pan and straw rack are supported for relative movement and reii'rlorcei in all directions against strain or displaremcnt.

lit is, ol course, to he understood that the various parts may he designed in other manners than illustrated and associated in other relations and may iti'inction somewhat dittercntly from that illustrated and, therefore, I do not desire to be limit-ed in any manner except defined in the ttl lptkiltltltl claims.
